CompilationManager should add Hadoop 2.x libraries to the classpath under Hadoop 2.x

Details

Description

The CompilationManager when compiling the generated Java file tries to add jar files that have JobConf fails if they are in the classpath, failing which adds hadoop-core.jar. hadoop-core.jar is not part of Hadoop 2.x. We need to add hadoop-common.jar and hadoop-mapred-client-core.jar

This situation is exasperated on Windows where the classpath presented to Sqoop actions under oozie does not have the full path but a uber jar because of command line length limitations and oozie sqoop jobs fail while compiling the generated jar files
